Performance failure of an evidence-based upper respiratory infection clinical guideline.

BACKGROUND: We evaluated an upper respiratory infection (URI) clinical guideline to determine if it would favorably affect the quality and cost of care in a health maintenance organization. METHODS: Patients with URI symptoms contacting 4 primary care practices before and after guideline implementation were compared to ascertain what proportion of all patients with respiratory symptoms were eligible for treatment in accordance with the URI guideline; what proportion of eligible patients were managed without an office visit; and what proportion of eligible patients were treated with antibiotics, before and after guideline implementation. RESULTS: A total of 3163 patients with respiratory symptoms were identified. Of these, 59% (n = 1880) had disqualifying symptoms or comorbid conditions for URI guideline care, and 28% (n = 1290) received disqualifying diagnoses on the day of first contact, leaving 13% (n = 408) who received a diagnosis of URI and were eligible for care in accordance with the guideline. Among this group of patients, the proportion who received guideline-recommended initial telephone care was 45% preguideline and 47% postguideline (chi2 = 0.40; P = .82). Likelihood of a subsequent office visit increased from pre- to postguideline (chi2 = 17.1; P <.01), although the majority of patients had no further diagnoses other than URI. Antibiotic use for the initial URI diagnosis declined from 24% preguideline to 16% postguideline (chi2 = 3.97; P = .046), but antibiotic use during 21-day follow-up did not change (F = 0.46, P = .66). The mean cost of initial care was $37.80 preguideline and $36.20 postguideline (P >.05). CONCLUSIONS: Only 13% of primary care patients with respiratory symptoms were eligible for URI guideline care. Among eligible patients, use of the guideline failed to decrease clinic visits, decrease antibiotic use during a 21-day period, or reduce cost of care to the health plan.     

Communication Practices and Antibiotic Use for Acute Respiratory Tract Infections in Children

PURPOSE

This study examined relationships between provider communication practices, antibiotic prescribing, and parent care ratings during pediatric visits for acute respiratory tract infection (ARTI).

METHODS

A cross-sectional study was conducted of 1,285 pediatric visits motivated by ARTI symptoms. Children were seen by 1 of 28 pediatric providers representing 10 practices in Seattle, Washington, between December 2007 and April 2009. Providers completed post-visit surveys reporting on children’s presenting symptoms, physical examination findings, assigned diagnoses, and treatments prescribed. Parents completed post-visit surveys reporting on provider communication practices and care ratings for the visit. Multivariate analyses identified key predictors of prescribing antibiotics for ARTI and of parent visit ratings.

RESULTS

Suggesting actions parents could take to reduce their child’s symptoms (providing positive treatment recommendations) was associated with decreased risk of antibiotic prescribing whether done alone or in combination with negative treatment recommendations (ruling out the need for antibiotics) [adjusted risk ratio (aRR) 0.48; 95% CI, 0.24–0.95; and aRR 0.15; 95% CI, 0.06–0.40, respectively]. Parents receiving combined positive and negative treatment recommendations were more likely to give the highest possible visit rating (aRR 1.16; 95% CI, 1.01–1.34).

CONCLUSION

Combined use of positive and negative treatment recommendations may reduce the risk of antibiotic prescribing for children with viral ARTIs and at the same time improve visit ratings. With the growing threat of antibiotic resistance at the community and individual level, these communication techniques may assist frontline providers in helping to address this pervasive public health problem.     

Association between health insurance and antibiotics prescribing in four counties in rural China.

A cross-sectional study was carried out at county, township and village health care facilities in four counties in rural China in order to describe and compare the effects of health financing systems on antibiotic prescribing in outpatient care. A total of 1232 outpatients at the health care facilities was selected by multi-stage random sampling and were interviewed over 2 weeks. The results showed that health financing systems appeared to influence antibiotic prescribing in outpatient care, both in terms of frequency and of the types prescribed. The insured group had lower prescribing of antibiotics at township and village health care facilities, and for respiratory tract infections, but had higher prescribing of newer antibiotics at county and village health care facilities, for respiratory tract and g-i infections. Because there was a high patient compliance rate (94.3%) in this study the prescribing of antibiotics (supply side behavior) reflected the use of antibiotics (demand side behavior) to a great extent. Thus the results imply that antibiotics prescribing and using might be biased by the patient's health financing systems and antibiotic prescribing was the result of the interaction between physicians and patients.     

Influencing antibiotic prescribing in general practice: a trial of prescriber feedback and management guidelines.

BACKGROUND: The extent of use of antibiotics to treat upper respiratory infections in general practice is an area for concern due to the increasing problem of bacterial resistance. Effective educational strategies to promote rational prescribing are needed. OBJECTIVES: We aimed to examine the effectiveness of prescriber feedback and management guidelines in reducing antibiotics prescribing by GP trainees for undifferentiated upper respiratory tract infection, and in improving the choice of antibiotic for tonsillitis/streptococcal pharyngitis. The research tested a stepwise approach to targeting educational input to high prescribers. METHOD: General Practice trainees in New South Wales (n = 157) were randomly allocated to a treatment group (n = 78) which received an education intervention on antibiotic use, or to a control group (n = 79) which received an intervention on an unrelated topic. Trainees completed three practice activity surveys, each of 110 consecutive patient encounters, with 6-month intervals between surveys. Prescriber feedback and management guidelines on use of antibiotics for URTI and choice of antibiotic for tonsillitis/streptococcal pharyngitis were delivered in a written form between surveys 1 and 2. An educational outreach visit to high prescribers occurred between surveys 2 and 3. Outcome measures were the rate of antibiotic prescribing for all indications, for URTI and prescribing of select antibiotics for tonsillitis/streptococcal pharyngitis. RESULTS: Antibiotic prescribing by the intervention group declined over three occasions from 25.0 to 23.3 to 19.7 per 100 URTI problems, while the control group increased from 22.0 to 25.0 to 31.7 per 100 URTI problems (P = 0.002). Prescribing in agreement with accepted guidelines for tonsillitis/streptococcal pharyngitis increased over time in the intervention group from 55.6 to 69.8 to 73.0 per 100 problems, but decreased in the control group from 59.6 to 57.5 to 58.5 (P = 0.05). CONCLUSION: Prescriber feedback and management guidelines were shown to influence antibiotic prescribing for URTI and choice of antibiotic for tonsillitis/streptococcal pharyngitis. This study provides a model for targeting educational input to those prescribers who most need to change their behaviour.     

Antibiotics and the Adult Sore Throat--An Unnecessary Ceremony

Herz M J. Antibiotics and the adult sore throat—an unnecessaryceremony. Family Practice 1988, 5: 196–199. Antibiotics are overprescribed for patients with sore throatsfor many reasons, including the difficulties in diagnosing thecause of the symptom, as well as the pharmacological and placebostrength of antibiotics. Two hundred adult patients presentingto one general practitioner were divided into two groups. Onegroup was given an antibiotic, the efficacy of which was stressed,and the other group was given symptomatic treatment with anexplanation that no antibiotic was needed. Six months afterthe initial consultation the patients' notes were checked forreturn visits with respiratory complaints. Significantly morepatients who received an antibiotic returned to the doctor withrespiratory problems, especially young men. During the study,few patients resisted either a high or low prescribing policy.It is concluded that antibiotic treatment for sore throats didnot prevent complications for the patient. Furthermore, highantibiotic prescribing created more work for the doctor by increasingthe repeat visit rate. Patients were equally compliant witha high or low antibiotic prescribing policy.     

Predictors of an antibiotic prescription by GPs for respiratory tract infections: a pilot

BACKGROUND: Antibiotics are over-prescribed for respiratory tract infections in Australia. OBJECTIVES: The aim of this study was to describe the clinical predictors of GPs' prescribing of antibiotics. METHODS: We used Clinical Judgment Analysis to study the responses of GPs to hypothetical paper-based vignettes of a 20-year-old with a respiratory tract infection. The nature of four symptoms and signs (colour of nasal mucous discharge; soreness of the throat; presence of fever; and whether any cough was productive of sputum) was varied and their effect on prescribing measured using logistic regression. RESULTS: Twenty GPs participated. The nature of each symptom and sign significantly predicted prescribing of an antibiotic. Cough productive of yellow sputum; presence of sore throat; fever; and coloured nasal mucus increased the probability of an antibiotic being prescribed. CONCLUSIONS: GPs are influenced by clinical signs and symptoms to use antibiotics for respiratory infections for which there is poor evidence of efficacy from the literature.     

Sore throat management practices of Canadian family physicians

OBJECTIVES AND METHODS: A survey was conducted of Canadian family physicians about their usual sore throat management practices. Physician knowledge, attitudes, beliefs and the effect of selected patient factors on variation in practices was assessed. RESULTS: The majority of physicians did not follow North American expert recommendations to usually take a throat culture and wait for culture results before prescribing an antibiotic. Similarly to the practices of family physicians in many countries, they favoured a clinical policy of selective use of throat cultures and decisions about the need for antibiotics based on clinical judgement. CONCLUSIONS: Physician practice site, demographics, knowledge, attitudes, beliefs and patient factors did not explain differences in approach. The implications for antibiotic utilization in the management of upper respiratory tract infections are discussed.
